After a thorough scientific review ordered in 2007 by the US Supreme Court, the US Environmental Protection Agency (EPA) issued a proposal with two distinct findings regarding greenhouse gases. The issuance of an endangerment finding enables the regulation of greenhouse gases under the Clean Air Act. Proposed Endangerment Finding.

exhaust from heavy-duty diesel engines meeting EPA 2007 and later emissions requirements—has found no evidence of carcinogenic lung tumors. The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology.
The bill also modifies the Clean Air Act to require the development of greenhouse gas emissions standards for all other mobile sources—e.g., A transitioning title intended to protect US consumers and industry and promotes green jobs during the transition to a clean energy economy.
